First of all it is not a case of specified profession bcz it can be an individual assessee and it is a company assessee. and company assessee is not eligible for sec 44AD and tax audit sec 44AB turnover limit exceed 1 cr.
Software services will come under engineering (which is a professional service) ?? and gross receipts are more than 50 lacs which is liable to tax audit
In sec 44ab there is nowhere mentioned that individual or company .There only mentioned as an assesse then the assessee can be an individual or a company ,it makes no difference
Plz refer sec 44AA and then Sec 44ADA then u will believe that specified professional is individual mentioned therein and sec 44AB talk about 50 lacs to such specified professional.
